It happens almost every time I try to download a torrent file for = example. Copying of large files over NFS seem not to trigger it, but I haven't = tested extensively. Here is the panic message : Fatal trap 12: page fault while in kernel mode cpuid =3D 0; apic id =3D 00 fault virtual address =3D 0x8 fault code =3D supervisor write data, page = not present instruction pointer =3D 0x20:0xffffffff80230413 stack pointer =3D 0x28:0xffffff80001e9280 frame pointer =3D 0x28:0xffffff80001e9510 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, long = 1, def32 0, gran 1 processor eflags =3D interrupt enabled, resume, = IOPL =3D 0 current process =3D 12 (irq19: sge0) trap number =3D 12 panic: page fault cpuid =3D 0 Uptime: 1d20h56m20s Cannot dump. Device not defined or unavailable Automatic reboot in 15 seconds - press a key on the console to abort Sleeping thread (tid 100039, pid 12) owns a non-sleepable lock My swap is on a zvol, so I don't have dump. I'll try to attach a disk on = the eSATA port and dump there if needed.=
